@William Carroll I think this ties back into what Neil said, I need to talk with local PMs/RE agents to verify what I believe to be market rent (I just looked on craigslist and padmapper and took an average) is indeed market rent. 10% vacancy in a D neighborhood may indeed be too low, another great question for a local PM.  

That will continue to push the averages up. 

The other potential issue is what if they aren't satisfied with the final product.  

Thank you how much in average can one experct in othe expenses apart from mortgage seeing that most people that get into troubler because they did not to the math right thank you So if the house or appartment is  100 000 RENT IS 1000 MORTGAGE IS  600 DOLLARSThen it is not worth it as 50 percent or 1000 is 500 if i understiid right thank you

Average rents around the area are 1100/mo.

If you decide to invest in these areas I would suggest that you do the same renovation that would be done in a good area, but with a lesser expensive products ( instead of hardwood we use strip vinyl with wood pattern).

Because you are selling a service based product.

What was the average time you went without rents between non paying evictees and vacancy? 

People like to think of themselves as being productive by looking for funding.

Different loan products have different criteria, some are more stringent than others - there are some loans you can't get if there is no furnace in place, if the kitchen is incomplete- that kind of thing.
